In 2012, BWSC filed a consent decree settlement with the Environmental Protection Agency (EPA), the Department of Justice, Massachusetts Department of Environmental Protection (MassDEP), and the Conservation Law Foundation to enhance its ongoing efforts to comply with the Clean Water Act and to clean and revitalize Boston Harbor and its tributaries, including the Charles, Neponset, and Mystic Rivers.
The Consent Decree expands the role of BWSC as an environmental steward for Boston’s waterways. BWSC has met or exceeded the benchmarks set by the Consent Decree and will continue to fulfill its commitments. The short-term and long-term measures are designed to improve water quality, increase public awareness and protect the environment.

National Pollutant Discharge Elimination System (NPDES) Permits
The National Pollutant Discharge Elimination System (NPDES) permit program was created in 1972 by the Clean Water Act (CWA). It addresses water pollution by regulating point sources that discharge pollutants to waters of the United States.
The CWA prohibits entities from discharging pollutants through a point source, such as a combined sewer or storm drain outfall, into a "water of the United States" unless they have an NPDES permit. The Environmental Protection Agency (EPA) issues NPDES Permits for Massachusetts. Permits contain limits on what the Permittee can discharge, monitoring and reporting requirements, and other provisions to ensure that the discharge does not impair water quality.
EPA has issued two NPDES Permits to BWSC: a Combined Sewer Overflow (CSO) and an Stormwater NPDES Permit.
BWSC's current CSO NPDES Permit, 2003, requires that BWSC comply with the EPA's Nine Minimum Controls and prohibits overflows from combined sewers in dry weather. Each year, BWSC submits a report on its compliance with the Nine Minimum Controls. Any overflows in dry weather, a rare occurrence, are reported to the EPA within 24 hours.
The CSO NPDES Permit also requires BWSC to submit an annual report. These reports have been submitted to the US EPA and Massachusetts Department of Environmental Protection since 1990.
One of the Nine Minimum Control requires that the public be notified of CSOs. Over the past several years BWSC has developed a web page that identifies when one of five of BWSC's CSO outfalls has discharged. Three of these outfalls discharge to the Fort Point Channel and two discharge into the Boston Harbor.
BWSC's Stormwater Permit was issued by the EPA in 1999. Under the Stormwater Permit, BWSC is required to develop and implement stormwater pollution prevention and management programs that are designed to reduce the discharge of pollutants to the municipal storm drainage system to the maximum extent practicable.
In addition, BWSC is required to report annually to the EPA and the Massachusetts Department of Environmental Protection (MassDEP) regarding the status of its pollution prevention and stormwater management programs. The annual report provide summaries of stormwater mangement activities undertaken by BWSC including, descriptions of the outfall screening, monitoring, and illegal connection remediation programs. Also included are BWSC's annual expenditures for stormwater programs and assessments of structural controls.
Municipal Discharge Permit
In accordance with Massachusetts Water Resources Authority (MWRA) Sewer Use Regulations municipal users of the MWRA sewer system must obtain and remain in compliance with a Municipal Discharge Permit issued by MWRA.
The MWRA Municipal Discharge Permit is issued annually to each of the 45 Municipalities discharging to the MWRA Sewerage System. The Municipal Discharge Permit is subject to MWRA Sewer Use Regulations 360 CMR 10.041-10.048, and it regulates:

- The discharge of toxic or hazardous materials such as pesticides and paints (prohibited)
- 8(m) permitting within an MWRA easement
- Discharge of residuals from sewer system cleaning (prohibited)
- Municipality must not allow discharges from a root\vegetation control project for its sewer maintenance program to enter its sanitary sewer unless it has a written authorization from the Authority
- Discharge from the installation of a cured-in-place pipe (CIPP) liner into a pipeline as part of a sewer rehabilitation project into the Municipal or MWRA sewerage system is prohibited, unless authorized by the Authority
